Abstract
An apparatus generally having a first circuit, a second circuit and a third circuit is disclosed. The first circuit may be configured to calculate a plurality of preliminary syndromes from a plurality of received symbols. The second circuit may be configured to calculate a plurality of normal syndromes by modifying the preliminary syndromes using at most two Galois Field multiplications. The third circuit is generally configured to calculate an errata polynomial based on the normal syndromes.
